Qwen 3.6-27B hits 5x speedup via DFlash

Speculative decoding is shifting from a luxury to a requirement for local LLM viability, and the DFlash release for Qwen 3.6 is a critical infrastructure update. Architectural changes in Qwen 3.6, specifically Causal Sliding Window Attention (SWA), broke compatibility with older speculators, causing the "PP speed" issues reported by early adopters. The new model from Z-Lab bridges this gap, offering a 3x-5x throughput increase on consumer-grade GPUs like the RTX 4090. While Qwen 3.6 has native Multi-Token Prediction (MTP), the DFlash speculator remains the gold standard for high-performance inference in specialized engines like vLLM and SGLang. This release makes the 27B model's "agentic coding" and "Thinking Preservation" features truly real-time for local developers.
